The survey asked participants to broadly classify the findings of each chest CT into one of the four RSNA COVID-19 imaging categories, then select which imaging features led to their categorization. Finally, the predator follows the levy flight distribution to exploit its prey location. In Dataset 2, FO-MPA also is reported as the highest classification accuracy with the best and mean measures followed by the BPSO. Imaging 29, 106119 (2009). Multiclass Convolution Neural Network for Classification of COVID-19 CT The MPA starts with the initialization phase and then passing by other three phases with respect to the rational velocity among the prey and the predator. and A.A.E. Also, because COVID-19 is a virus, distinguish COVID-19 from common viral . all above stages are repeated until the termination criteria is satisfied. The shape of the output from the Inception is (5, 5, 2048), which represents a feature vector of size 51200. CNNs are more appropriate for large datasets. The test accuracy obtained for the model was 98%. Biol. According to the best measure, the FO-MPA performed similarly to the HHO algorithm, followed by SMA, HGSO, and SCA, respectively. Sahlol, A.T., Yousri, D., Ewees, A.A. et al. (3), the importance of each feature is then calculated.

Average of the consuming time and the number of selected features in both datasets. However, WOA showed the worst performances in these measures; which means that if it is run in the same conditions several times, the same results will be obtained. It can be concluded that FS methods have proven their advantages in different medical imaging applications19. Abbas, A., Abdelsamea, M.M. & Gaber, M.M.

Also, all other works do not give further statistics about their models complexity and the number of featurset produced, unlike, our approach which extracts the most informative features (130 and 86 features for dataset 1 and dataset 2) that imply faster computation time and, accordingly, lower resource consumption. The MCA-based model is used to process decomposed images for further classification with efficient storage. Inf. If the random solution is less than 0.2, it converted to 0 while the random solution becomes 1 when the solutions are greater than 0.2. 7, most works are pre-prints for two main reasons; COVID-19 is the most recent and trend topic; also, there are no sufficient datasets that can be used for reliable results. Johnson et al.31 applied the flower pollination algorithm (FPA) to select features from CT images of the lung, to detect lung cancers. 43, 635 (2020). https://doi.org/10.1038/s41598-020-71294-2, DOI: https://doi.org/10.1038/s41598-020-71294-2. The prey follows Weibull distribution during discovering the search space to detect potential locations of its food. I am passionate about leveraging the power of data to solve real-world problems. In this experiment, the selected features by FO-MPA were classified using KNN. \delta U_{i}(t)+ \frac{1}{2!
